Outside barriers can be a good earn, especially if it has a backmarker in it [Ice Chariot's two group wins at Brisb. were a standout from outside barriers for those who knew it was a backmarker].

To narrow things down a bit more as to where you plonk your hard-earned, just check out the outside barrier horse's history [you all know where but I can't mention the name of the site] and see where it usually is on the turns in it's past races and which barriers the horses wins came from mostly. If it has been running from inside barriers for it's last couple of starts and loosing and now find itself in an outside barrier, the odds will be good because it will be in the perfect barrier, yet few punters will know it.

If it gets back and wins mostly from the outside[ish] barriers, it's a backmarker [basically, avoid leaders from outside barriers and backmarkers from inside barriers]. Blindly backing outside barrier runners that might have a leader or on-pacer in it, is like backing horses running in glue-on shoes. A waste of good betting money..
